Why Did I get Rejected from Princeton EA? (High Stats + ECS?)

Princeton is a huge reach for all applicants. As noted, those that were deferred will most likely get rejected.

Don’t take the rejection personally and don’t compare yourself with classmates. Even if you think you know their stats, you don’t know everything about them or how they packaged their application.

It would be highly unlikely that a GC would sabotage an application.
